MILK BUCKETCOVER AND STRAINER Filed Sept. 7, 1937 Patented Sept. 5, 1939UNITED STATES PATENT OFFICE 3` Claims.

My invention relates to milk bucket strainers and has for its object toprovide a new and efcient cover and screen for milk buckets.

A further object is to provide a milk bucket and strainer which willkeep all foreign material from dropping in the bucket from the air orfrom the sides of the cow and which will therefore provide a sanitarycover for the bucket.

A still further object is to provide a milk bucket cover which has aremovable screen set therein and adapted to be removed for cleaning toenable the dairy man to keep it entirely clean and sanitary and topermit the use of a cloth strainer therein if desired for any local lawrequirements.

A still furth-er object is to provide a milk bucket cover carrying aflange to fit in the bucket and with a screen or perforated screeningmedium mounted therein at an angle to prevent the milk from splashingall over the legs of the milker due to the force of milk hitting thestrainer.

These objects I accomplish with the device illustrated in theaccompanying drawing in which similar numerals and letters of referenceindicate like parts throughout the several views and as described in thespecication forming a part of this application and pointed out in theappended claims.

In the drawing Figure 1 is a side elevation of the milk bucket cover.

Figure 2 is a plan View thereof.

Figure 3 is a section on line 3-3 of Figure 2.

Figure 4 is a side view of the removable strainer.

Figure 5 is a diametrical section of a modiiied type of strainer inwhich the strainer is not removable but, in which the screen on theoutlet spout is mad-e removable.

In the drawing I have shown the device as an inwardly curved dome-shapedbody A, having a central opening 5 therein through which the milk isintroduced into the bucket. The outer edge of the dome A is a flangedbase 6 to make a flange to fit over the top of the bucket and preventany chance of dirt entering the bucket from the top.

Depending around the dome and spaced in from the flange 6 is a frustumshaped flange 8 adapted to t into the open top of a milk bucket. Withinthe dome A and spaced in from the flange 8 there is a dependingcylindrical chamber 9 with the walls IU thereof cut off on the bottom IIof the cylinder at an angle to the horizontal base of (Cl. E10- 155) thedome A. Into this chamber 9 and iitting the walls Ill, I then provide afilter member B having sides forming a cylinder I2, said cylinder havingthe bottom partially closed at an angle identical to that of the anglecut II on the bottom of the walls I Il. The greater area of this bottomis made of porous material such as screen Wire I3 or perforated sheetmetal filters.

A discharge spout I5 is mounted on one side of the dome A preferably inthe side on which the least angle of the cylinder I0 is formed. Thisspout I5 is secured over a screened opening I6 to insure no dirtentering the bucket through the spout to aid the aeration of the milkbeing poured from the bucket and act as a double screening for the milkboth keeping it clean and aiding in the cooling of the milk.

In Figure 5 I have shown the dome as AI, the spout as I8 and within thedome I provide a permanently secured screening member BI. member isprovided with either perforated metal base I9 or a screen (not shown),The outlet spout I8 is provided with a slot 20 therein in which aremovable screen 2I is inserted to close the opening 22 of the spout.

It will be obvious that such changes and modiiications may be made inthe construction as that shown in Figure 5 without departing from thevspirit of the invention or the scope of the claims.

Having thus described my invention I desire to secure by Letters Patentand claim:

1. In a milk strainer, the combination of a dome shaped body having acentral opening through the top and carrying a depending flange aroundthe perimeter of the body on the under side to t into the top of abucket; a depending cylinder on th-e under side of said dome, saidcylinder being of greater diameter than said opening in said dome shapedbody to prevent splashing of the milk from the opening; and a screenmember formed of a cylinder to fit said .depending cylinder and aslanting screen bottom to strain the milk after it enters the centralopening.

2, A milk strainer of the class described, comprising a dome shaped bodyhaving a ange around its perimeter to rest upon the top edge of abucket; a depending inwardly tapered flange extending down from saidbody to t within the inner face of the top of the bucket; a cylindersecured to the inner side of said dome-shaped body, said cylinder beingof greater diameter than the opening through said dome-shaped bodyforming a splash flange in the space between the opening in saiddome-shaped body and This 20 the inner perimeter of said cylinder, thebottom of said cylinder being cut 01T on an angle; a spout extending outfrom one side of said domeshaped body for pouring milk from said bucket;a screen in the mouth of said spout; and a perorate bottom mountedacross the angled end of said cylinder to screen all milk entering thebucket.

3` A device as set out in claim 1, including a screened spout from whichthe milk may be poured from the bucket.
